Arrangement structure of stirrups at main girder and secondary beam joint

Abstract

This invention provides a stirrup arrangement structure at the main beam-secondary beam joint. The main beam reinforcement bars are arranged along the length of the main beam, and the stirrups are tied around and bound to the outer perimeter of the main beam reinforcement bars. The secondary beam reinforcement bars are arranged along the length of the secondary beam, and the stirrups are tied around and bound to the outer perimeter of the secondary beam reinforcement bars. At the connection point between the main and secondary beams, the upper secondary beam reinforcement bars are tied to the main beam reinforcement bars. Bottom and top U-shaped stirrups are also tied around and bound to the outer perimeter of the main beam reinforcement bars, and the two are interconnected by a sleeve-threaded structure to form a complete ring. This invention largely solves the problem of difficult and misaligned stirrups at the main beam-secondary beam joint, effectively improving the first-pass yield rate and increasing structural safety. This invention not only effectively solves common quality problems at the main beam-secondary beam joint, ensuring high-quality construction, but also achieves significant results in improving construction efficiency and reducing project costs.

Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a stirrup arrangement structure at the joint of primary and secondary beams. Background Technology

[0002] Reinforced concrete beam joints, as key components of concrete structures, often become challenging areas to construct due to concentrated stress. The dense arrangement of stirrups in these areas makes quality control difficult, leading to frequent quality problems. On-site issues frequently arise, such as misplaced or omitted stirrups at the primary and secondary beam joints, resulting in decreased construction quality. Furthermore, insufficient stirrup quantity in the core areas of primary and secondary beams weakens the joint's load-bearing capacity, potentially causing damage. This damage not only affects the overall stability of the structure but may also threaten the building's safety. Therefore, during construction, it is crucial to pay close attention to the stress conditions of the joint area to ensure that the joint can effectively transfer and bear various loads. To this end, this invention designs a novel stirrup arrangement structure for primary and secondary beam joints. Utility Model Content

[0005] A stirrup arrangement structure at the joint of a main beam and a secondary beam includes joint stirrups, main beam reinforcement, main beam stirrups, secondary beam stirrups, and secondary beam main reinforcement. The main beam reinforcement is arranged along the length of the main beam, and the main beam stirrups are tied around the main beam reinforcement. The secondary beam reinforcement is arranged along the length of the secondary beam, and the secondary beam stirrups are tied around the secondary beam reinforcement. At the joint between the main beam and the secondary beam, the secondary beam reinforcement at the upper part of the secondary beam is tied to the main beam reinforcement. The joint stirrups are a two-segment structure, arranged around the main beam reinforcement.

[0006] Furthermore, the node stirrups include bottom U-shaped stirrups and top U-shaped stirrups arranged around the main reinforcement of the main beam. The bottom U-shaped stirrups are welded and fixed to the main reinforcement of the main beam. The two ends of the bottom U-shaped stirrups are threaded structures, and the two ends of the top U-shaped stirrups are provided with sleeves that match the threaded structure.
